The Ibis Hotel suffered minor to moderate damage during the Canterbury earthquake sequence ongoing since 2010.

Post-earthquake inspections of the building revealed the presence of lap splices in potential plastic hinge regions of beams that were not in accordance with the original structural drawings and which did not comply with New Zealand Standards.

Compusoft Engineering Ltd. (CEL) was engaged to determine through the use of an inelastic time history analysis whether the Ibis Hotel building could achieve 67%NBS (or greater) with the performance of the lap splices considered.
